Skunk2 Alpha Series valve springs (Honda D-Serie SOHC VTEC engines)

Skunk2 is proud to introduce its Alpha Valve Spring for Honda's K/F-series VTEC engines. Each kit includes Skunk2's high-quality dual valve springs that are the result of nearly two decades of racing and engine building experience.

Each Alpha Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm.

Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. During development, each valvetrain component is tested both on the dyno and the road, including 11,000 rpm drag racing engines and 17,000 rpm superbikes. Manufactured from the best materials available, Skunk2 valvetrain components provide exceptional performance, reliability, and quality and remain standard-issue on each Skunk2 vehicle that we build and support.
